Description
Technical Field
The invention relates to the technical field of wires and cables, in particular to a salt corrosion resistant and torsion resistant control cable.
Background
A signal cable is a signal transmission means. The signal cable has a very small transmitted signal, so as to avoid the signal interference, the signal cable is provided with a shielding layer outside, the shielding layer of the wrapped conductor is generally conductive cloth, a woven copper mesh or copper foil (aluminum), the shielding layer needs to be grounded, an external interference signal can be guided into the ground by the shielding layer, the interference of the interference signal entering the inner conductor is avoided, and the loss of the transmitted signal is reduced.
The sensor signal cable is subject to tin-plated or silver-plated conductors. The sensor signal cable has four layers of protection, namely an insulating layer, a shielding layer, a winding layer and a sheath layer, and only ensures accurate transmission of weak electric quantity signals. Insulating layer: the physical and chemical properties equivalent to those of the sheath layer can eliminate the sheath, the shielding net and the winding layer in a narrow environment, and the sheath, the shielding net and the winding layer can be independently used as a lead. Winding layer: the wrapping layer is a selected polymer material that is primarily intended to prevent damage to the insulating layer by the shielding mesh. The mechanical properties of the cable as a whole are also enhanced. A shielding layer: in order to successfully derive the interference signal from the metal material (copper or tin-plated copper), the extremely thin metal wire must have sufficient bending resistance to prevent metal debris from affecting other electrical devices. Sheathing layer: excellent mechanical performance and can resist metal impact and cutting with higher strength. Has very high tensile strength and can resist repeated bending for a long time.
The salt corrosion resistant and torsion resistant control cable is generally used for electric power, lighting, control and communication transmission wires and cables of various ships in river and sea and offshore or offshore buildings.

And the existing cable is easy to cause accelerated abrasion of a cable protection layer after being subjected to marine multi-salt, acid and alkali corrosion, oil stain corrosion and seawater humidity resistant impregnation. The condition that the protective layer is torn is easily caused by unstable fixation of the wire core in the protective layer when the sea wind power generation is twisted, and the service life is shortened.
